friend constexpr /右值引用/ iter_move ( const basic_const_iterator & i ) noexcept ( /* 见下文 */ ) ;		(C++23 起)

将底层迭代器解引用的结果转换为其关联的常量右值引用类型。

返回类型 /*rvalue-reference*/ 是 std:: common_reference_t < const std:: iter_value_t < Iter > && , std:: iter_rvalue_reference_t < Iter >> 。

函数体等价于
return static_cast < /*rvalue-reference*/ > ( std :: ranges:: iter_move ( i. base ( ) ) ) ; 。

此函数对普通的非限定查找或限定查找不可见，仅当 std:: basic_const_iterator < Iter > 作为参数的关联类时，才能通过实参依赖查找找到该函数。
